I cleared the cache and data from the MagicLocker app and that did the trick, until MagicLocker went though the setup process again, and then the home button issue popped up again.
So I uninstalled MagicLocker completely and that seems to have fixed the issue.
I guess there was an update to MagicLocker or something and that caused the home button to screw up...?
Weird.
Hopefully it stays fixed. Damn shame...I was a fan of MagicLocker.
